Answer:
The foaming in the elephant toothpaste demonstration means that a gas is produced. Production of a gas is a clue that a chemical reaction has occurred. The water vapor in the genie-in-a-bottle demonstration also shows the production of a gas.
I think it’s B. Strawberry’s can be propagated asexually by allowing plantlets on the end of runners.

Answer:
The correct answer is C) selective transport through nuclear pore complexes
Explanation:
Nucleus is the place where the replication and the transcription of DNA occurs. The process of translation in eukaryotes occurs in cytoplasm therefore RNA has to come out of the nucleus.
Nuclear pore complexes are the openings in the nuclear membrane from where these molecules come out in the cytoplasm. Small RNA like tRNA directly comes out through binding directly to export receptors but large RNA like mRNA forms ribonucleoprotein particles which involves class-specific adaptor proteins for transport. So the right answer is C.
